Ehci linux driver

Part Number: AM Tool/software: Linux Hi, Omap EHCI usb driver not able to detect usb flash device and mouse and keyboard on custom am target board. There are two failure modes: "usec" have passed (major * hardware flakeout), or the register reads as all-ones (hardware removed). * * That last failure should_only happen in cases like physical cardbus eject * before driver shutdown. But it also seems to be caused by bugs in cardbus * bridge shutdown: shutting down the bridge before the. The HC * should pick up where it left off in the TD, unless a Set Transfer Ring * Dequeue Pointer is issued. * * The TRBs that make up the buffers for the canceled URB will be "removed" from * the ring. Since the ring is a contiguous structure, they can't be physically * removed. Instead, there are two options: * * 1) If the HC is in the middle.

Main kernel source; uhci on Linux or kernels, uhci-hcd on Linux kernels (For kernels there's also the older usb-uhci driver, from the Acher/Fliegl/Sailer team.) OHCI: Working; mostly stable. kernels support non-PCI versions for various ARM, MIPS, and PPC System-on-Chip embedded Linux platforms. The changes I've made were to switch the xHCI HCD (USB ) support and EHCI HCD (USB ) support options in Device Drivers- USB support from built-in to module. From what I understood from the terminal output, I cannot not build the xhci into the kernel. Here is the output.
